The construction is correct, it does not "plastoc" and nothing moves inside unlike some other "no name" I could not be without. The Accu done its job but over time I expect him to judge the quality / price ratio. I would have given it one extra star if its dimensions were more adjusted: it enters easily into the compartment but the D60 to get out, it's more complicated: obliged to give a rap on the edge of the box of hand and out.
